Air-conditioning
Multi-split air-conditioning in Brisbane
A multi-split runs several indoor heads from a single outdoor condenser. It suits properties where you want cooling in three or four rooms but cannot fit, or do not want, three or four separate outdoor units.

It is often the right answer for apartments and townhouses with one small balcony or plant area, and for older homes where roof space rules out ducted.
What it covers
What's included.
Room by room sizing
Each head sized for its own room, and the outdoor unit sized for the combination.
Outdoor unit siting
One condenser positioned for airflow, service access and noise, which matters more when it is the only one.
Head positioning
Each indoor head placed for airflow across its room rather than where the pipe run is easiest.
Pipe routing
Multiple refrigerant runs planned back to one location, kept tidy and clipped.
Electrical work
Circuit and isolation handled under the same licence as the refrigerant work.
Commissioning
The system evacuated, charged and each head checked before handover.
Why people call
Common reasons for this job.
- Three or four rooms need cooling
- There is only one practical spot for an outdoor unit
- Body corporate rules limit outdoor unit numbers or positions
- Roof space or access rules out ducted
- Separate splits would mean several condensers on a small lot
- An extension has added rooms to cool
How Hoff works
The approach.
The outdoor unit position gets the most attention, because with a multi-split there is only one and every room depends on it. Airflow, service access and noise to bedrooms and boundaries all factor in.
Hoff will tell you honestly when separate splits would serve you better. Multi-splits tie rooms to a shared system, and where only two rooms need cooling, two independent splits are often the more sensible answer.
For apartments and townhouses, check body corporate requirements before committing. Hoff can tell you what the installation involves so you can put an accurate proposal to them.
Refrigerant work requires ARCtick authorisation (Hoff holds L169731) and the electrical side requires an electrical contractor licence (90673). Both are held by the same person. Electrical work is tested and certified, and equipment carries its manufacturer warranty.

Multi-split questions.
Not automatically. Multi-splits save outdoor space and are ideal where only one condenser will fit. Separate splits keep rooms independent, so a fault in one does not affect the others. It depends on the property.
It depends on the unit and the combined capacity of the rooms. Sizing is done from the rooms, then the condenser is selected to suit.
Each head is controlled separately, though on most multi-split systems all heads share a mode. Hoff will explain the limits of the specific system being quoted.
For apartments and townhouses, usually yes. Hoff can describe the installation so you can put an accurate request forward.
Sometimes, particularly when rooms are used at the same time. Where only one room runs at a time, separate splits can be the better performer.
